SPECIFICATION forming part of Letters Patent No. 767,452, dated, August 16, 1904,

Application filed ,pril 2, 1904. Serial No. 201,270. (No model.)

To all 11/71/0117, it may concern.-

Be it known that I, ROBERT WV. STROUT, a citizen of the United States, residing in Salem, in the county of Essex and State of Massachusetts, have invented an Improvement in Shaving-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to a machine for treating hides, skins, and leather, and is especially designed and adapted to be used for shaving skins.

In machines of the class described the skin is shaved by means of a bladed cylinder or roll which is revolved at a substantially high rate of speed.

The present invention has for one of its objects to provide a machine of the class described with which the imperfections in the skin caused by the chattering of the rapidlyrevolving bladed cylinder or roll may be avoided, or at least reduced to a minimum. To this end the bladed cylinder is journaled in the sides of a box-like frame, which is cast in one piece, is of rigid construction, and firmly braced.

Another feature of the present invention consists in providing a machine in which the operating parts are reduced in number, and for this purpose the bladed roll or cylinder and the rotatable grinder are driven from the same shaft, which may be the main shaft of the machine.

The invention further has for its object to provide for simultaneously stopping rotation and travel of the grind ing-wheel without stopping rotation of the bladed cylinder or roll, thereby economizing in the power employed to operate the machine and diminishing the wear and tear upon the grinding-wheel, its operating parts, and the bladed cylinder or roll. Provision is made for adjusting the grinder with relation to the bladed cylinder or roll.

These and other features of this invention will be pointed out in the claims at the end of this specification.

Figure l is a side elevation with parts broken away of a machine embodying this invention; Fig. 2, a rear elevation of the machine shown in Fig. 1 looking toward the right; Fig. 3, a vertical section on the line 3 3, Fig. 2; Fig. 4:, a detail in plan and section, on an enlarged scale, to be referred to; Fig. 5, a vertical section on the line 5 5, Fig. 2; Fig. 6, a detail in elevation, on an enlarged scale, to be referred to; Figs. 7 and 8, sectional details, on an enlarged scale, to be referred to; and Figs. 9 and 10, details to be referred to.

In the machine herein shown as embodying this invention the hollow box-like frame or casing is preferably cast in one piece and comprises side walls a 7) and end walls 0 (Z, connecting said side walls and having a crosspiece or top wall 6 connecting the sides a Z) near their upper ends and extended from the rear wall 0 toward the front wall (Z to leave an opening f, (see Fig. 5,) which is substantially closed by a movable top g, fitted to slide on the side walls a I) and provided with a detachable hood or bonnet it, having an opening 2', which is normally closed by a cover 1' on the outer side of the said hood or bonnet.

The side walls a b are provided with beveled upper edges is, (see Figs. 2 and 7,) which are embraced by correspondingly-beveled side flanges l, depending from the movable top Q The side walls a b are extended upward beyond the end wall 0 to leave a space between the top 9 and the'cross-piece e, in which is lo cated a rack-bar n, secured to the crosspiece e and engaged by a gear or pinion 0, fast on a vertical shaft 1), extended up into a hollow upright or standard q, attached to the top and provided with an enlargement at its upper end to form a chamber 1', provided with a removable cover 5- and in which is located a worm-gear 2?, fast on the spindle or shaft 1) and engaged by a worm w on a horizontallyextended shaft 10, supported in a hollow arm or boss 12, extended horizontally from the hollow standard 9, the said worm-shaft being pro vided with a hand-wheel 13, by turning-which rotation may be imparted to the vertical shaft 9 and its gear 0, which latter engages the fixed 5 bracket 54, attached to the side 5.

rack-bar 11, and thereby causes the sliding top r to be moved forward or backward, so as to engage a grinding wheel or disk 15 with a 1'0- tatable bladed or cutting cylinder 16. The cutting-cylinder 16 is journaled in lixed bearings carried by the side walls a b at their front upper end, and the grinding-wheel 15 is mounted to slide on a shaft 17, (see Fig. 7,) which is square or other than round in cross-section intermediate of its journals 18, which latter are supported in boxes 19, attached to the movable top g, one of said journals having fast to it a pulley 20, (see Figs. 1, 2, and 7,) which is connected by a cross-belt 21 (indicated by dotted lines, Fig. 1) with a pulley 22, normally loose on a shaft 23, having fast on it a pulley 24, one at each side of the machine. (See Fig. 2.) The pulleys 24 are connected by belts 25 with the pulleys 26 on the ends of the bladed cylinder 16. It will thus be seen that the grinding-wheel 15 and cutting-cylinder 16 are driven from the same shaft 23, which is provided with fast or loose pulleys a y.

The grinding-wheel 15 is movable longitudinally on the shaft 17 by means of a forked lever 28, (see Fig. 7,) the said lever having its hub 29 mounted to move longitudinally on a sleeve 30, fitted overa shaft 31, provided with helical grooves 32 33, extended in opposite directions and into which projects a fork or curved piece 34, (see Figs 7 and 9,) having a pin or stud 134, carried by the under side of the hub 29 and extended through a longitudinal slot 35 in the under side of the sleeve 30, which constitutes a pivot for the lever 23, and, as shown in Fig. 7, is mounted to turn on the journal-bearings 37 for the shaft 31. The sleeve 30 acts as a guard or cover for the grooved shaft 31 and prevents the grooves thereof from becoming filled up with emery and metallic dust, which would render the machine inefficient and in time inoperative.

The shaft 31 may be rotated,as herein shown, by means of a bevel-pinion 40, fast on it and in mesh with a like pinion 41, fast on an inclined shaft 42, supported in suitable bearings 43 44, attached to the side a of the casing or hollow frame, the shaft 42 having at its lower end a worm or spiral gear 45, which meshes with a worm 46, (see dotted lines,Figs. 1 and 4,) fast on a shaft 47, supported in bearings in the sides a b. The shaft 47 beyond the side 5 of the ,hollow easing has loose on it a pulley 49, (see Figs. 2, 4, and 5,) adapted to be renderedf ast thereon by a clutch of any suitable construction, one member, 50, of which is attached to the hub of the pulley 49 and the other member, 51, of which is keyed to the shaft 47 and is adapted to be moved into engagement with the member 50 by a spring 52, supported by the hollow frame and engaging a lever 53, which is connected with the clutch member51 in the usual manner, the lever 53 being pivoted to a The lever 53 is provided with a tailpiece or arm 55, with which cooperates a cam 56 on a rock-shaft 57, (see Figs. 3, 4, and 6,) supported in suitable bearings attached to'the side 7) and provided with a crank arm or handle 58. The cam 56 acts to turn thelever 53 so as to disengage the clutch member 51 from the member 50 against the action of the spring 52, and thereby render the pulley 49 loose on its shaft 47, consequen tl y stopping rotation of the grooved shaft 31 and travel of the forked lever 28. The rock-shaft 57 is designed to simultaneously control the rotation of the shaft 17, and for this purpose the rock-shaft 57 is provided with a second cam 60, which may be made, as herein shown, by cutting away a section or portion of the shaft, (see Fig. 4,) which cam cooperates with a rod 61, sliding through the side 7) of the frame and attached to a clutch-lever 62, which is forked to engage studs or pins 63 on the opposite sides of a collar 64, mounted on the main shaft 23 to slide thereon.

The shaft 23 is made hollow at its end (see Fig. 8) to receive a pin or rod 65, which at its inner end has extended through it and a slot 165 in the shaft 23 a key 66, which engages the collar 64. The pin or rod 65 has mounted on it at its outer end a metal disk 67 and afiber washer 68, which are adapted to engage the hub 69 of the pulley 22, the washer 68 and disk 67 being retained on the rod 65 by nuts 70.

The pulley 22 is normally loose on the shaft 23, and, as shown in Fig. 8, the said shaft is provided with a sleeve 71, upon which the pulley 22 is mounted, the pulley 24 being rendered fast to the shaft 23 by a key 73 or in any other suitable manner. The pulley 22 is provided with an inclined peripheral flange 74, which cooperates with the inclined under surface of the rim of the pulley 24, and when the inclined flange 74 is brought into engagement with the inclined surface 75 of the rim of the pulley 24 the norl'nally loose pulley 22 is rendered fast to the pulley 24, which latter is fast on the shaft 23. The pulley 22 is rendered fast to the pulley 24 by movement of the clutch-lever 62 in the direction indicated by the arrow 77 in Figs. 2 and 8,

which is effected by the full portion of the.

cam 60 engaging the rod 61, as shown in Fig. 6, which takes place, herein shown, when the cam 56 is withdrawn from the lever 53, and the latter is turned by the spring 52 to clutch the pulley 49 onto the shaft 47. In other words, in the present instance the earns 56 60 are arranged on the rock-shaft 57 so as to act reverselythat is, when the cam 56 is not acting on the lever 53 the cam 60'is act-- ing on the rod 61, and vice versa. The normally loose pulley 22 may be disengaged from the fast pulley, as herein shown, by helical springs 80, inserted in pockets 81 in the hub 69 of the pulley 22, said springs encircling pins or rods 82, provided with heads 83, which extend through the end walls of the pockets and engage the hub of the pulley 2 1, as shown in Fig. 8.

The rock-shaft 57 is supported in suitable bearings 8 1, attached to the side 50f the boxframe, and its handle 58 may be located at its front end, so as to be accessible to the operator from the front of the machine.

It will thus be seen that the operator through the handle 58 has control of the grinding-wheel 15, so that by moving the said handle from its upright position (shown in Fig. 3) into a position which may be substantially diametrically opposite the rotation and the traverse of the grinding-wheelmay be stopped without interrupting the rotation of the cutting cylinder or roll 16, which is desirable in this class of machines, as it enables the grinder to be stopped at any point of its traverse, thereby economizing in the power employed to operate the machine, and the wear upon the blades of the cutting-cylinder and also upon the grinder may be diminished by turning the feed-wheel 13 so as to move the grinding-wheel backward and out of contact with the cutting-cylinder. The grinder can be again set in motion to travel lengthwise of the cylinder by the operator moving the handle 58 into the position shown in Fig. 3.

The box-like frame has cast integral with it an extension 90, upon which are erected arms 91 92, to which are pivoted levers 93 94, which are connected by cross pieces or bars 95 96. (See Fig. 4c.) The cross-piece 95 has pivotally secured to it at its center a yoke comprising a bar 97 and upright arms 98, in which latter is journaled the bed-roll 99 of any suitable or usual construction, the bar 97 being mounted to turn in a substantially horizontal plane to adjust the bed-roll in parallelism with the knife-cylinder. This adjustment may be effected by the screws 100, carried by the arms 101, attached to the cross bar 95, said screws engaging the cross-bar 97 of the yoke on opposite sides of its pivot 102.

The levers 93 9 1 may be turned on their pivots to move the bed-roll toward the knifecylinder when it is desired to shave a hide or skin placed over said bed-roll by a foot-treadle 103, having an arm carrying a screw 10 1,

which engages the rear side of the cross-bar 96, and said bed-roll may be returned to its normal position away from the knife-cylinder 16 by a spring 105, encircling a rod 106 within a tube or cylinder 107, which is attached to a cross-bar 108, connecting the uprights 91 92. The cylinder 107 is closed at its outer end by a threaded plug or cap 109, against which bears the end of the spring 105, the other end of which bears against a washer or collar 110, fast on the rod 106, which extends loosely through the cap or plug 109 and through the bar 108 and is screw-threaded beyond the said bar and engaged by a thumb-nut 112, which cooperates with the cross-bar 108 and constitutes a stop to limit the forward movement of the bed-roll 99 toward the knife-cylinder 16. When the bed-roll 99 is in its forward position, (represented in Figs. 1 and 5,) the spring is compressed, and when the pressure of the foot is taken off from the treadle 103 the said spring acting against the collar 110 eflects movement of the bed-roll away from the knife-cylinder.

It is to be observed that the spring 105 is located in a closed cylinder and is protected from dirt, &c., and is thereby kept in good Working condition and is prevented from becoming inoperative.

By reference to Fig. 5 it will be seen that as the sliding top Q is moved to adjust the grinding-wheel with relation to the knife-cylinder it carries with it' the shaft 17, which causes the forked lever and its sleeve 80 to turn, thereby effecting the tension on the cross-belt 21, and when the grinding-wheel 15 is moved away from the knife-cylinder the cross-belt is slackened. The slack in the crossbelt is taken up by an idler-pulley 120, carried by a crank or arm 121, fast on a rockshaft 122, which is supported in bearings 123, attached to the end wall 0 of the box like frame, and is restrained from longitudinal movement by the collars 124: on said shaft. The rock-shaft 122 is turned in the proper direction to keep the pulley in engagement with the cross-belt 21, and thereby automatically take up the slack in said belt, by a helical spring125, encircling the rock-shaft and having one end fastened to a bearing 123 and the other end to a collar 126, fast on said rockshaft.

By reference to the drawings, and especially Fig. 5, it will be seen that the box-like frame cast in one piece affords a firm and solid support for the knife-cylinder 16, which is thereby enabled to be driven at a substantially high speed with the least possible chattering or vibration, thus reducing to a minimum the imperfections in the skin due from this source.
